EQUIPMENT REQUIREMENTS
4. Equipment Required. Table 2
identifies the
specific equipment to be
used in this
calibration procedure. This equipment is issued with Secondary Transfer Calibration
Standards Set AN/GSM-287. Alternate items may be used by the calibrating activity when
the equipment listed in table 2 is not available. The items selected must be verified to
perform satisfactorily prior to use and must bear evidence of current calibration. The
equipment must meet or exceed the minimum use specifications listed in table 2. The
accuracies listed in table 2 provide a four-to-one ratio between the standard and TI. Where
the four-to-one ratio cannot be met, the actual accuracy of the equipment selected is shown
in parenthesis.
5. Accessories Required. The
accessories listed in table 3
are issued as
indicated in
paragraph 4 above and
are used in this
calibration procedure. When necessary, these items
may be substituted by equivalent items, unless specifically prohibited.
